.TIRE COVER Filed June 5, 1932 INVENTOR Patented Dec. 6, 1932 PATENT OFFICE ROBERT my, 0] DETROIT, IIGHIGAN TIRE GOV-EB Application fled June 8, 1982. Serial No. 615,188.

This invention relates to tire covers and more particularly to means for stiffening, binding, protecting and ornamenting the circular inner edge of the face ring of a tire cover.

The principal object of this invention is to provide a tire cover havinga face rin of rigid, form sustaining, material, prefera ly, though not necessarily, of a composltion disclosed and described in my copending application Serial No. 611,620, filed May 16, 1932, the inner edge of the face ring being provided with a metallic molding, substantially as disclosed in another copending application, Serial No. 573,241, filed November 5, 1931, of which the instant application is a continuation in part.

Still further objects of the invention will become readily apparent upon reference to the following detailed description of preferred embodiments of the invention and to the appended drawing, in which- Figure 1 shows a tire cover of the invention;

Figs. 2 and 3 are transverse sections as if on lines 22 and 3-3 of Figure 1;

Fig. 4 shows, to enlarged scale, a portion of another tire cover of the invention;

Fig. 5 is a transverse section as if on line 5 5 of Figure 4; and

Fig. 6 is a modified form of the parts shown in Fig. 5.

Referring to the drawing, it will be seen that there is disclosed in Figs. 1 and 2, a tire cover having a face ring 10 made of a rigid, form-sustaining material, which is preferably, though not necessarily, of the nature disclosed in my application Serial No. 611,620, filed May 16, 1932. One of the characteristics of a tire cover face ring made of this material is that its inner edge is subject to deformation and shredding. This characteristic is also true, to a lesser extent however, of tire covers made of thin sheet metal where deformation and'edge splitting often occurs.

In order to reinforce the inner circular edge of the face ring, there is provided on such edge a welt 12 secured thereto by rivets 5o 14, although it will be understood that other suitable means of securing such welt to the edge may be used if desired. For concealing thewelt, and also for receiving, protecting, binding and ornamenting the inner circular edge of the face ring, there is provided a channeled molding 16 preferably, though not necessarily, of the cross section disclosed, other channel cross sections being found useful in this connection. For example, the o0 molding might be so cross sectioned as to hook around welt 12 and be in actual interlocking engagement with the same.

Various methods of securing the moldin 16 to the face ring 10 may be suggested and 05 several such methods are disclosed. One, and perhaps the simplest method, is to make the channel 16 of such form, temper, and material that it will have an inherent tendency to expand as it is snapped into place on the inner edge, the channel receiving the welt 12 and such inner edge. This method is shown in my copending application Serial No. 573,241 and for this reason the instant application is truly a continuation in part of the latter.

If desired, rivets 18 may be used, as in Fig. 3, to secure ring 16 at its ends to the faces.

Another method of securing the channel so ring 16 to the face ring 10 is to make the channelof such a form, material and temper, that it will have a tendency to contract. In such a case the molding, which is designated by the reference 20, Figure 4, normally has a diameter slightly less than the diameter of the inner edge of the face ring and must be expanded, when applied to the face ring, to assume the position of Figure 4. For maintaining the channel ring 20 expanded, means in the nature of a screw bolt 22 is threaded through the welt 12 and the face ring 10 and between the endsv 24 of the channel 20. A

shoulder 26 on the bolt is engaged by the ends 24 of the channel rin and tends to maintain the channel expande The boltmay, if desired, be provided with a medallion head 28 of ornamental characteristics which overlaps and conceals the ends of the face ring and which also serves to conceal the working parts of the bolt and to protect the entire construction at this point. If desired the bolt 22 may have a nut 32 as in Fig. 6.

third metho of securing a channel to 1.5 the edgeof a face ring of a tire cover would be to provide the ring of Figure 4 with an inherent tendency to expand, in which case the bolt. 22 would be used to lock the moldin in place on the face ring. In such 20 a modi cation, when it is desired to remove the'channel, it would be necessary first to remove the bolt 22 and then manually pull the channel ring 20 off the face ring. This is not true of a construction wherein a normally contracted molding is employed, for in this latter construction the molding, once released by the removal. of bolt 22, would tend to remove itself frorn'the face ring 10.

Other methods of securing the channel ring to the face ring might be suggested and specific mention of these will not at this time be attempted.

Now having described the invention and a referred embodiment thereof, reference will e had to the following claims which alone define and limit the invention, and it will be understood that the same is not to be limited to the specific details and constructions herein shown. m
